• Average particle sizes (the number average is specified) of the polyurethane dispersions were determined after dilution with deionized water by means of laser correlation spectroscopy (instrument: Malvern Zetasizer 1000, Malver Inst. Limited).
• the pH was measured by the method described in DIN ISO 976 on the undiluted sample.
• the hair tresses were washed with 0.3 g of a commercial silicone-free shampoo (Syoss “Volume Lift Shampoo”) at 38.5° C. for 1 minute.
• the hair tresses were then rinsed at 38° C. for 1 minute and combed through with a conventional comb (broad side).
• the hair tresses were then dried with a hairdryer for 1 minute at ca. 75° C.
• Syntran PC 5100 (INCI: Polyacrylate 21 (and) acrylate/Dimethylaminoethyl Methacrylate Copolymer), commercially available from the supplier Interpolymer, aqueous solution, solids content 25%
• a washed hair tress (European straight hair tresses, prepared as described in step 0) was placed in a bowl standing on a balance. 1g of a 2% by weight (solids content) aqueous solution was distributed over the entire length of the hair tress so that the solution was distributed as homogeneously as possible. The hair tress was then combed until it was completely wetted. The tress was then smoothed with 2 fmgers. This was then twisted on a perm rod with a gap between 2 and 3 mm. The untwisting was carried out clockwise with the help of a weight attached to the end of the tress. The hair tress was then fastened with an elastic band. All finished tresses were then hung in the 50% humidity chamber. The tresses were dried in the humidity chamber for at least 18 hours.
• the tresses were unwound counterclockwise on one side.
• the length of the tresses was determined as LS.
• Lockenhaltentalk ⁇ ⁇ in ⁇ ⁇ % 100 ⁇ ( L ⁇ ⁇ 0 - LT ) ( L ⁇ ⁇ 0 - LS )
• Table 1 shows examples of inventive mixtures 1-b to 1-d in comparison with non-inventive mixtures of components (V1) in the form of product A 1-a and (V2) in the form of product B 1-e. It can be clearly seen that product A alone, which is not in accordance with the invention, has a very low moisture resistance for curly hair, as shown in example 1-a. The same applies to product B alone, which is not in accordance with the invention, in example 1.e. In both examples, 1-a and 1-e, only a curl retention capacity of around or less than 30% is achieved.
• the water resistance could be significantly increased, which is shown in the percentage curl retention capacity figures of 47 to 73% for the mixtures 1-b to 1-d. Furthermore, it can be seen that the curl retention capacity with a 1:1 mixture 1-b of component (V1) and (V2) has a maximum for the measured mixtures.
• the mixture 2-a (inventive) allows a significantly better water resistance, measured both with wet and dry hair.
• the hair was then dried by hair dryer for 3 minutes at 75° C. and straightened with a commercial flat iron 5 times at 230° C. for 3 seconds and then completely dried at 56% rel. air humidity at 23° C. for 12 hours.
• the width of the respective straightened tress was determined for the determination of BG.
• the tress was then dipped in a water bath at 38° C. for 30 seconds, then the tress was hung up and completely air-dried at room temperature. The width of the tress was then measured again for the determination of BW.
• Mixture 3-c showed neither water resistance nor shampoo resistance.
• Mixture 2-b showed better water and shampoo resistance but the hair tended to stick together, resulting in a not very aesthetic appearance of the hair.
• mixture 3-a shows very good water and shampoo resistance (even after 2 shampoo treatments) of the straightening of the hair, without the hair sticking together.
• hair treated with mixture 3-a felt very soft (like healthy hair) and looked very natural.
